7 Application filed Augustli3, 19 29 fiseria This invention relates to an improved construction of spraying device. 7 r Spraying devices as customarily constructed are provided with one or more suction tubes through which liquid is adapted to be drawn from a reservoirinto position to be struck by a blast of air and atomized into theform of spray. It is an object of this invention to provide a construction of suction tubing which shall beof increased efiiciency,

of a high degree of strength and with the elements thereof maintained in permanent adjustment. 1 Other objects will be apparent from the specification and from the accompanying drawings in which 1 Fig. 1 is a front'ele'vation of a spraying.

Fig. 2 is a section taken along the line a II'II of Fig. 1,

Fig. 3 is a transverse section taken along the line- III-III of Fig. 1 through the suction tubingpand Fig. 4 is a transverse section taken along 25 the line IV-IV of Fig. 1 through the suction tubing. i o

Referring particularly to the drawings, in

its preferred embodiment, the device comprises a gas supplying means or compressor 30 including a barrel 1, a piston head 2, ai piston' rod 3, and a handle 4. A plurality of blast openings 5 are provided in the head of the.

A reservoir 6 isrigidly associated barrel. with the barrel 1.

A tubular structure is provided for conducting liquid from the reservoir into posi- I tion to be struck by a blast of air issuing from the blast openings 5. Thetubular structure comprises a plurality of tubes 7, connect- 4G with a tubular main or body portion 9. The

tubular structure is rigidly securedto the head of the barrel 1 by means of solder or the like. It is positioned with the main 9, extending into the reservoir 6 and terminat- 7 ing adjacent the bottom thereof in position to be submerged in liquid introduced into the reservoir. The tubes 7 lie with their discharge ends terminating exteriorly of and adjoining the blastopenings. In the emboditubes 7 can be formed ed by webs 8, and having fluid communication spray with a ment i11u$itted3kh mainKora-body vided with a bore a of smaller diameter, generally cylindrical in hapeg In 'utilizingythe device any suit able liquid;

The con tacting portions of the structure are secured by solderor otherwise. It will-be understood! that the tubular structure can be formed in any other suitable manner; for-examplethe H separately from the body portion 9 and secured thereto by soldering or in any other suitable manner.

The unitary construction of suction tube described is possessed of a high degree of strength and is resistent tofforces tending to dislocate the same. constituting the suction tubing are accurate ly spaced and permanently maintained in ad- JLlStGd position. The greater'portion ofthe The constituent tubes suction tubing constituted by'the main or body portion is ofenlarged bore byreason of which the likelihood of the suction tubing clogging with sediment is reduced'to a'mini r5 inumz The shape of the bore of the suction 9 tubing permits liquid .toybe drawn therethru in a thin column and easilylbroken into a fine 7 minimum of air volume and pressure.
